Polyether Polyols for Pipeline Series 1. Description This series of polyether polyols is special for pipeline series. 2. Typical foam properties | Type | P1101 | P1201 | P2101 | P2201 | P3101 | | Types of blowing agent | H2O | H2O | HCFC-141b | HCFC-141b | CP or CP/IP | | Production process | Pouring | Pouring | Pouring | Spray | Spray | | POL:ISO | 100:130-150 | 100:100-105 | 100:110-120 | 100:110-120 | 100:100-105 | | Appearance | Pale yellow liquid | Pale yellow liquid | Pale yellow liquid | Pale yellow liquid | Pale yellow liquid | | Temperature ℃ | 18-25 | 18-25 | 18-25 | 18-25 | 18-25 | | Cream time/s | 20-60 | 6-10 | 20-60 | 6-10 | 20-60 | | Gel time/s | 90-240 | 15-30 | 90-240 | 15-30 | 90-240 | | Free foam density kg/m3 | 28-38 | 40-60 | 24-35 | 40-60 | 24-35 | | Molding foam density kg/m3 | ≥65 | ≥70 | ≥65 | ≥70 | ≥60 | | Thermal conductivity mW/m·k | 30-33 | 28-33 | 28-33 | 28-33 | 28-33 |
3. Typical product characteristics | Type | Product features | | P1101 | Water blown, ozone depletion is 0, green; excellent flow
properties, good density, flow properties than ordinary pipe system
well over 10% of the blowing agent; excellent physical properties
of the foam, through the national resistance to creep; no situation
brittle foam shrinkage, good adhesion and clip kepi. | | P1201 | Full water foaming, zero ozone depletion potential, and extremely
low climate warning potential. Continuous production can be
realized, the efficiency is high, the thickness of the foam layer
and the outer protective tube can be adjusted according to needs,
and the comprehensive cost is low; the polyurethane material is
foamed in the axial direction, the fow distance is short, the foam
distribution is uniform, and the pipeline performance is optimal. | | P2101 | Better flow properties of materials, widely used in various heat
pipe insulation layer, for urban central heating and insulation to
provide a variety of fluid transfer systems, articles by CJ/T
114-2000 standard test; foam has excellent insulation properties,
good compressive strength and density distribution, and superior
temperature performance and durability, resistance to aging,
excellent creep. | | P2201 | The product can meet the continous production process, and
has the characteristics of high efficency, low feed quantity, low
cost, low thermal conductivity and uniform density distribution.
The performance of the prepared pipeline is optimized. The super
large diameter pipes can be realized by adjusting the thickness of
foam layer and outer protection tube. | | P3101 | Zero ozone destruction potential and extremely low global warming
potential. Fine foam, low thermal conductivity and excellent
mechanical properties. Through the adjustment of catalyst and
cyclopentane, the production of pipes with different diameters can
be satisfied. |
4. Packing and storage Products use iron drum packing, net weight 200kg; Tons of barrels
packaging, net weight 1000kg. The shelf life is 6 months from the produciton date. |
